Ok, this bit isn't true; apparently this is happening during normal
runtime as well, so it's probably not related to the amq.direct
exchange.  It looks like any call to tx_commit is hanging, when called
from anywhere in the system.  I could really use some sort of advice
for how to debug this.  It's rabbit 2.1.0 on erlang 13.2.4 (erl
-version gives 5.7.5; I can never remember exactly how that maps to
erlang's crazy versions: 13B4 maybe?).
